ADHD, OCD, and PTSD are among my diagnoses. Also ADHD subscores are super high on inattentiveness 🤟

Guided meditation is pretty important for me. If it's not guided I find myself trying and trying, but I keep standing up, or my mind wanders and I forget what I was doing. I go lie down again, but before long I find myself following through on some random thought. It's a dance that rarely works well. Though it can during certain periods. Especially if I have integrated it well into my day - that is, I know when I'm going to meditate and ease off tasks before, and I know what I will do after.

This video, which I found in the meditation community here, is a pretty good example of what works.

Just focusing on my breath. Letting thoughts, sensation and all that come and whatever, but keep returning focus to the breath, without trying to change anything and just doing it until the end.

I still have many days where I just can't get into it, and don't even manage to stay on the floor for the twenty minutes or whatever time I set. But other times it works great. I consider it a success if I manage to stay on the floor at least the entire time :)

I think if you've been in a somewhat meditative state before, it will be easier to understand what it's about and how to get there.

I personally like to scan through my body too. Just focusing awareness in there, maybe starting with how it touches the ground. Which has a pretty strong relaxing effect.

Last piece of info from my experience that might be worth sharing: I had a great yoga instructor to get started and her guided meditation was on point. She let myself do all the exploring, but supported it. So it's more like "And when you are ready... ok I see maybe we wait a bit". Whereas someone I met later wouldn't notice much what was happening with me and just pushed me through their practice, which is pretty much the same as if I had a recorded meditation running.

Good luck and hope you have some good sessions to enjoy :)
